That page seems to have mislead you. CockroachDB is by nature a distributed database. That’s true of the Core and Enterprise versions. For more insight into how fundamental operations are distributed, you can read our architecture docs, or read through our core benefit tutorials.
RESTORE, however, is a special case. This specific feature is only available with an Enterprise License. It minimizes the impact to a cluster’s performance by distributing backup and restore work to all nodes.
A non-distributed backup alternative that doesn’t require an enterprise license is the SQL Dump feature.
Hope that adds clarity for you. If you have any other questions, please let me know.
